Abstract

Una película microporosa orientada que comprende una resina de poliolefina incluyendo un polímero a base de propileno con unidades de polipropilenoatáctico y por lo menos alrededor de 40% en peso de la película es un material de relleno, en donde el manterial de relleno incluye partículas que tienen untamano de partícula que contribuye a la formacion de poro. También se refiere a un método para preparar una película polimérica microporosa con poliolefinasflexibles. El método incluye preparar una resina de poliolefina que incluye un polímero a base de polipropileno que contiene unidades de polipropilenoatáctico, preparar una resina rellena de un material agregando por lo menos alrededor de 50% en peso de la película de un material derelleno, a dicharesina de poliolefina, dicho material de relleno incluye una pluralidad de partículas solidas que tienen un tamano de partículas que contribuye en laformacion de poros, preparar una película a partir de dicha resina rellena yorientar dicha película. La película puede incorporarse dentro de un laminadoen donde una capa de soporte es preferiblemente unida con adhesivo o por puntos a la película; también pueden usarse en artículos tales como los panos y batasquirurgicos asícomo en varios artículos de prenda, ya sea como el artículo completo o simplemente como un componente del mismo.An oriented microporous film comprising a polyolefin resin including a propylene-based polymer with tactical polypropylene units and at least about 40% by weight of the film is a filler material, wherein the filler material includes particles having a particle size that contributes to pore formation. It also relates to a method of preparing a microporous polymeric film with flexible polyolefins. The method includes preparing a polyolefin resin including a polypropylene-based polymer containing tactical polypropylene units, preparing a resin filled with a material by adding at least about 50% by weight of the film of a filler material, to said resin of Polyolefin, said filler material includes a plurality of solid particles having a particle size that contributes to pore formation, preparing a film from said filled resin, and orienting said film. The film may be incorporated within a laminate where a backing layer is preferably bonded or adhesive bonded to the film; They can also be used on items such as surgical gowns and robes as well as various articles of clothing, either as the entire item or simply as a component thereof.
